MSN-50 is a Bax and Bak oligomerization inhibitor. MSN-50 efficiently inhibits liposome permeabilization, prevents genotoxic cell death and promotes neuroprotection[1][2].
MSN-50 (0~10 uM) inhibits dye release from liposomes in a concentration-dependent fashion. MSN-50 (0~40 uM) inhibits tBid/Bax-mediated MOMP (mitochondrial outer membrane permeabilization) in a concentration-dependent manner and shows concentration-dependent inhibition of Bak-mediated MOMP. MSN-50 inhibits both Bax and Bak after activation by either cBid or Bim. MSN-50 (5 μM; BMK cells) inhibits apoptosis induced by actinomycin D and staurosporin (STS)[1][2].
